Energy-efficient data synchronization for cooperative context-aware computing

In cooperative context-aware computing, the synchronized context information among devices is critical to the system performance. In this work, we propose an energy efficient context synchronization scheme using the reference-credit concept. Simulation results show that it improves energy efficiency by approximately 50% compared to the legacy random synchronization scheme which is popular in use. The proposed scheme can be employed as a key context synchronization function of the context-aware devices and computing platforms.
